Was tempted to post this on the Linux/Unix subforum, I think the hardware board would be better fitting for those who may consider one.
Last week Woot had the 14" HP Chromebook w/200mb T-Mobile Faux 4G for $199, after shipping/taxes ~$220. Still better than buying just a T-Mobile 3G/LTE modem for rare non-free wifi travels.
Intel Celeron 2955U
2x USB 3.0 Ports
1 USB 2.0 Port
Headphone-Mic hybrid jack
SDHC Slot (spring loaded, SDHC card stays inside)
SIM Card Slot/T-Mobile 3G Modem
Weight ~4.2 lb (similar to a 12" PowerBook G4)
Generally I wouldn't touch HP products, however I heard great things about the trackpad and keyboard so the risk was worth taking--earlier I was eying a Windohs running Celeron/i3 with a built-in modem but why bother paying a Windows license tax if you don't plan to use it or help Microsoft inflate their Windows 8 sales numbers?
Speed wise ChromeOS is snappier than I remember(Parallels allows you to download/use a ChromeOS disk image), did some browsing, done a few work tasks on GoogleDocs, played some music from my Google Music account... still managed to squeeze ~8 hours. Microsoft "Cloud" seemed to choke on OneDrive document listing refresh/save. Wifi reception better than most HPs relatives owned/work issued which is a nice plus. Sound is much better on a desk/lap than any HP I've seen/used-no distortion at 90% volume
Switched it to developer mode, Crouton install went smoothly and began testing to see how much battery life would vary. After usage of Libre Office, Inkscape, GIMP, some Firefox it was slightly better(9.5 hours). This would make a perfect battery friendly Linux portable, build quality is above most $400 Windows PCs & zero plastic creaking. I still had ~8GB free space so 16GB SSD isn't too cramped unless the next ChromeOS update gains bloat to expand Android features.
Seen negative comments on the screen, viewing angle is better than my dads' HP DM4 and the screen isn't as glossy. Webcam is useless so I stuck a piece of tape on it.
Would it replace a full blown notebook?
Nope, I still need my daily workflow of Dreamweaver, Illustrator, Logic Pro X/Pro Tools & MS Office 2011. I needed a cheap HDMI equipped notebook vs always needing the silly Mini Display Port to HDMI for my MBP. Smooth for Hulu & Netflix... which my old Thinkpad would choke on.
